The hottest new brain scanner based on sensors has

  • Detail

A new brain scanner based on sensors has been successfully developed in the United States. Recently, researchers at Massachusetts General Hospital and Siemens medical systems are jointly developing a new brain scanner. In the future, the new equipment may reveal more secrets about fear, happiness, disease and other conditions

it is predicted that the images provided by the new brain scanner will have higher resolution and better effect than those provided by all commercial devices on the market at present. By placing multiple sensors in the brain, the device can produce accurate images in a very short time, which will eventually help diagnose diseases such as Alzheimer's disease and epilepsy

neuroscientist johngabrieli said, "brain imaging may be the most influential R & D project for the next few years, especially because Siemens is commercializing its technology. If we can get a more accurate view of the brain, human beings will take a big step forward."

generally speaking, doctors can export these data through RS232 port at the same time. The nuclear magnetic resonance (MRI) machine in the hospital medical center usually has 12 coils, but the new equipment under development has 96 coils, so it will form a dense arrangement on the scalp. Lawrencewald is a biophysicist at Massachusetts General Hospital. His team worked with Siemens to develop the new device. "Each coil captures only a small part of brain information, so it is necessary to place a large number of small detectors on the head, whose performance is seven times higher than that of existing commercial adsorbents," he said Each coil measures a small but highly accurate spin signal in the brain tissue structure, and then the computer stitches the images together to form a high-resolution brain image

new technology helps diagnose epilepsy and Alzheimer's disease

these multi-channel devices have provided help to some patients with epilepsy. In an initial original study, neurologists found abnormalities in two-thirds of epilepsy patients studied. The previous brain scan results of these patients showed "normal", so the doctor decided that they were not ill (in fact, they were ill, but they were not detected). The detection of the new equipment allows these patients to receive further neurosurgical treatment. For patients, early detection of symptoms is very important for their treatment

at present, scientists are using new technologies to study Alzheimer's patients. Wald believes that in diseases such as Alzheimer's disease, basic diagnosis cannot be carried out based on images. "We hope to be able to observe the small spacing in the brain, which will produce some additional diagnostic information, and maybe monitor the effect of drug treatment."

patients suspected of Alzheimer's disease can undergo MRI examination to exclude other neurological diseases that cause disease symptoms. However, recent studies have shown that subtle changes in neurology have increased the risk of disease. These changes may include the atrophy of the hippocampus, an important area of memory, and the cortex, which is important for memory and higher cognitive function. Detecting these changes requires long-term scanning to produce high-quality data, which is impossible in daily clinical practice. "New technologies are expected to change this limitation," said braddickerson, a neuroscientist at Harvard Medical School At the same time, he also reminded that it will still take several years to realize the daily clinical use of new technologies. "We are rapidly entering a new era, and then we can identify the abnormalities of Alzheimer's disease based on these data."

in depth study of brain functional control areas

new equipment is likely to have important applications in functional magnetic resonance imaging (fMRI). FMRI is a method that uses MRI to measure the rapid and minimal metabolic changes of the brain targeting the active part of the agricultural film market. You can consult the manufacturer. FMRI will show the blood flow in the most active part of the brain, which can be used as an indirect method to measure activity, while standard MRI only tracks a change in brain blood flow. FMRI technology is usually used to locate brain tissue that controls special functions, such as areas that control language and motor functions. The first clinical application of the new device is likely to be the same as fMRI, which will be used in the surgical design of neurosurgery. "Surgeons want to know whether the functional areas of language and movement are involved when they remove a brain tumor, and the more accurate, the better," Bundy said

new instruments may also affect our basic understanding of the brain. Gabrieli believes that the spatial resolution of fMRI is somewhat limited. Using higher resolution images, scientists can determine the basic neurological knowledge of all aspects of cognitive function. Gabrieli said that he was happy to find out whether some tiny structures in the deep brain played an important role in emotion regulation, such as regulating different emotions, such as fear and happiness

at present, Siemens is carrying out the commercialization development of 32 channel array equipment in Massachusetts General Hospital, and it is expected to launch products later this year. Wald and colleague Graham Wiggins have developed new scanners with more channels, including 96 channel and 128 channel arrays. Wald proudly declared, "using these new devices for brain imaging can achieve the highest resolution!"
